Problem

Two substances, A and B, initially at different temperatures, come into contact and reach thermal equilibrium. The mass of substance A is 6.23 g and its initial temperature is 20.6 oC. The mass of substance B is 25.6 g and its initial temperature is 52.5 oC. The final temperature of both substances at thermal equilibrium is 46.6 oC.

If the specific heat capacity of substance B is 1.17 J/g oC, what is the specific heat capacity of substance A?
